SOLE-LAYING MACHINE.

SPECIFICATION forming part of Letters Patent No. 595,097, dated December7, 1897.

Application filed October 9, 1896. Serial No. 608,401. (No model.)

To @ZZ whom it may concern:

Be it known that I, CHARLES S. GooDING, of Brookline, in the county ofNorfolk and State of Massachusetts, have invented certain new and usefulImprovements in Sole Laying or Pressing Machines, of which the followingis a specification.

This invention relates particularly to 1nachines for pressingcement-coated outer soles against lasted uppers of boots and shoes andholding the soles against the uppers while the cement is setting orhardening.

The invention consists in certain improved mechanism for jacking theshoe by hand and also for applying power to press the shoe-sole againstthe upper after it has been jacked.

The invention further consist-s in certain improvements in the jack orholder for the lasted boot or shoe, whereby the saine may be quickly andeasily adjusted to conform to various sizes and shapes of lasts.

Referring to the accompanying drawings, forming a part of thisspecification, Figure l is a front elevation of my improved sole-layingmachine, one of the jacks being shown raised and the other depressed.Fig. la is a detail view of the crank-shaft. Fig. 2 is aside elevationof the machine, one side of the supporting-frame being removed in ordermore clearly to illustrate the mechanism. Fig. 3 is an enlarged plan,partly in section, taken on line 3 3, Fig. l. Figs. l and 5 are detailelevations illustrating the guide-roll of the jackcarrying arm indifferent positions. Fig. 6 is a section on line G G, Fig. 2. Fig. 7 isan enlarged end elevation of my iin-proved jack. Fig. 8 is alongitudinal section of the jack, taken on line S S, Fig. 7.

Like letters refer to like parts throughout the several figures of thedrawings.

In the drawings forming a part of this speciiication, a a represent sidestandards or frames which serve to support the working parts of themachine. The lower cross-head Z) is connected to the upper cross-head cby the stayrods CZ CZ. The stay-rods d d are clamped at d' a to thestandards ct a and are fastened at e c to the middle cross-head e. Thecrosshead c is formed with turrets c c to receive flexible pressers orforms c2 c2, said pressers being of any suitable construction.

The driving-shaf t Z9' rotates in bearings b2 ZF in the cross-head Zi.At one end of the shaft ZJ is a pulley b3. Said pulley rotates looseupon the shaft ZJ and is providedwith a conical face b4, adapted toengage the conical face h5 upon the clutch-pulley U1. The pulley Z'IG isfast to the shaft b and is encircled by a brake or friction strap ZF.

The pulley Z13 is forced lengthwise of the shaft ZJ into contact withthe clutch-pulley Zf or out of contact therewith by means of the collarbs, screw-threaded sleeve ZJ, and nut D10. The nut Z210 is connected bythe link 611 to the arm Z912. Said arm b12 is fast to the rock-"shaftD13. The rock-shaft D13 has bearings at D14 b1* in the lower crossheadZ) and in the bracket Z115, said bracket being fastened to the floor.

The treadle Z116 is fast to the rock-shaft ZJ1 and is provided with afriction-roll D17, which turns on a pin Z918 in a sliding pin Z119. Thesliding pin Z91J fits in a recess formed in the treadle Z311 and ispushed upwardly against a cam Z127 by the spring Z920. rA crosspin b21prevents the pin Zi11 from turning in the treadle Z916.

Upon the driving-shaft ZJ' is a pinion-gear 22, which meshes with a gearD23. Said gear is fast to a shaft b2, having bearings at Z325 D25 in thecross-head b. Upon the shaft Z221 are formed two cranks Z226 Z22 at anangle of one hundred and eighty degrees with eachother.

The cranks 626 Zig are in line with the center line of the turrets c cand each receive and impart motion to a jack. Each jack comprises twolast supporting standards f f. The standard f is provided with aspring-pin f2 and supports the heel portion of the last g. The standardf is provided with a toepiece f3 to support the toe of the same, thetoe-piece f3 being adjustable vertically to conform to varying shapesand sizes of lasts.

The standards ff are each formed with a rectangular base f1, dovetailedto lit a groove or guide in the rectangular slide-block f5. Upon each ofthe standards fj is fastened a rack f6, which meshes a gear f7, theracks being upon opposite sides of the gear. The gear f7 is fast to aspindle fg and is turned by means of a hand-Wheel f8. The spindle f9 hasa bearing in the bracket f 10, said bracket f1@ being fastened by screwsto the slide-block f5. It is evident that by turning the handle ICO f2the gear f7 will be rotated and the standards ff' will be caused toapproach or recede from each other in order to fit varying sizes oflasts. Vhen the standards have been brought to the desired distance fromeach other, they are locked in position by the setscrew f1.1.

The slide-blockj5 is formed to slide in horizontal ways f12 upon theupper end of a vertical slide f11. Said slide f14 is guided in ways f16upon a swinging arm f16, the lower end of which is attached to the crankb26 by the cap f17. The slide f11 is moved up or down upon the arm f16by the lever f18 and arm f26.' f1S and f2@ are pinned to the rock-shaftf1, said rock-shaft having bearings f21f21 on the arm f16, and areconnected to the slide f14 by the links f22f22. The lever f18 is lockedin position by the spring-pawl f2s, which engages the rack f24, fast tothe arm f26. A guide-roll f26 upon the slide f11 engages a groove e2upon the cross-head e when the arm f16 is in a vertical position and theslide f11 is raised, as shown in Figs. 2 and 5. Vhen the slidef14 islowered, the roll f25 passes out of the groove e2, and the arm f16 maythen be tipped forward upon the crank Z226 into the position shown indotted lines, Fig. 2, as hereinafter explained.

The operation of the machine as a whole is as follows: The arm f16 beingtipped out in the position shown by dotted lines, Fig. 2, the operatorplaces the cement covered shoe thereon. He then places the outer soleupon the shoe in its proper location and pushes the arm into a verticalposition, as shown in Fig. l, on the left-hand side of the machine. Theoperator holding the arm in position with the left hand pushes down uponthe handle of the lever f18 with the right hand, thus raising the shoeto the position shown in Fig. 2 and in the right-hand side of Fig. l,bringing the shoe-sole against the presser c2 by means of the links f22and locking it in position by the pawl f26 and rack f21. Vhen in thisposition, it will be observed that the link f22 and the short arm 0f thelever f18 form'a toggle-joint, so that when the last is raised in theposition shown in Fig. 2 the link and the short arm of the leverapproach a straight line, joining the points at which they are pivotedto the slide f11 and the swinging arm f 16, respectively. It will thusbe seenthat the shoe can be firmly pressed against the presser-pad c2 bya comparatively slight pressure upon the end of the long arm of thelever f16. Having jacked the shoe, as described, the operator depressesthe treadle Z216, thus forcing the conical face of the pulley Z23against the conical face of the clutch-pulley Z26 by means of therock-shaft Z212, arm Z212, link Z211, nut Z216, sleeve Z29, and collarZ22. The friction-strap Z27 is at the same time released by means of thearms Z222 Z222, fast to the rock-shaft Z213, their outer ends beingsecured to the strap Z27. When the treadle is depressed, the cam-rollZ217 is withdrawn from the depression in the cam Z227 until theperiphery of the roll nearly clears the outer periphery of the cam. Thepulley Z22, through the clutch, turns the shaft Z2', and through thegears Z222 Z223 the crank-shaft Z221 is rotated, forcing one of the armsf16, with its last and shoe, upward against its correspondingpresser-pad and lowerin g the other arm and releasing it from thepressure applied by power. The shoe which is released is then loweredstill farther by unlocking the pawl f2s and raising the outer end of thelever f18 until the guideroll f26 clears the groove c2, when theoperator pulls the arm f 16 toward him, tipping said arm upon the crankZ226 into the position shown in dotted lilies, Fig. 2, the arm beingstopped at this point from falling forward by the link f26, which ispivoted to the arm f 16 at f27 and encircles the stay-rods CZ d, acollar f28 upon one ofthe stay-rods serving` to hold up the link f26.When the arm f16 is brought to the position shown in dotted lines, Fig.2, and while the shoe upon the other arm or jack is under pressure, theoperator removes the shoe from the jack, which is tipped forward, placesanother thereon, and repeats the abovedescribed operation.

The clutch is automatically thrown out and the rotation of the machinestopped by the cam Z227, as follows: As soon as the operator has loweredthe treadle until the clutch is thrown in, as described, the cam turnsand locks`the treadle down and the clutch in until another depressionupon the cam, located at one hundred and eighty degrees from the iirstdepression, comes opposite the cam-rolLwhen the spring Z229 on thetreadle raises the same and the roll enters thedepression in the cani,throwing out the clutch and applying the friction brake or strap Z27 toovercome the momentum of the machine. In order to keep the clutch firmlypressed together and to allow for slight variations due to wear, theroll Z217 does not quite clear the outer periphery of the cam when theoperator depresses the treadle, so that when the cam is turned by theclutch the roll Z217 is pressed down, compressing the spring Z220 andholding the clutch firmly in place until the roll comes opposite thenext depression in the cam, as described.
